How can I change my username?

The person who held this position before me put her name as the username, and we are still using the same forms, so I don't want to create a new account, but I would like to change the username to something more generic. 

Hi,

Though we do not allow users to change their own username, we can change it for you.  Let us know a few of your choices, in order of preference and we will be happy to change your username if one of your choices is available.

I would like to change my username from knieman to kirkwoodparks if it is available. Thank you!
